Question

i have following class:

public class FirstClass 
{
   public FirstClass()
   {
       list = new List<SomeType>();
   }

   public List<SomeType> list;
}

Is this possible to do some actions like fire different method after someone will put element into that list?

Answer 1

You should use a ObservableCollection<SomeType> for this instead.

ObservableCollection<T> provides the CollectionChanged event which you can subscribe to – the CollectionChanged event fires when an item is added, removed, changed, moved, or the entire list is refreshed.
